AI Summary

This cross-sectional observational study asked how cannabis use disorder, alcohol use disorder, psychological distress, and suicidal ideation relate to one another within broader social and demographic contexts. Researchers conducted a secondary analysis of nationally representative 2021 survey data from 44,360 participants using network analysis. The abstract does not report quantitative effect sizes or prevalence estimates.

Sociodemographic factors such as age and sexual orientation had more direct connections with mental health outcomes, while social conditions including housing instability and employment were positioned more distally in the network. Cannabis use disorder and psychological distress emerged as key bridging nodes connecting these contextual factors with suicidal ideation and alcohol use disorder. The findings support viewing mental health as shaped by interacting individual and structural factors, but because the data are cross-sectional, this study cannot establish causation, directionality, or whether targeting these nodes would improve outcomes. This is an abstract-based summary and does not assess the full text.

The network connected cannabis use disorder and psychological distress with suicidal ideation and alcohol use disorder, but the cross-sectional design supports association—not causation or a proven pathway.

📄 Original Abstract

BACKGROUND: Alcohol and cannabis use disorders are among the most prevalent substance use disorders worldwide. They frequently co-occur and show high comorbidity with psychological distress and suicidal ideation. Although these relationships are well established, their underlying structure remains unclear, as mental health is embedded within a complex network of individual, social and environmental factors. The aim of this study was to explore the interplay between alcohol and cannabis use disorders, psychological distress and suicidal ideation within the context of sociodemographic factors and social determinants of mental health using network analysis. DESIGN: Cross-sectional secondary analysis of nationally representative survey data. METHODS: Data were drawn from the 2021 National Survey on Drug Use and Health (N = 44,360). A mixed graphical model was estimated and partitioned into three communities (psychological, sociodemographic, social determinants of mental health). Bridge centrality and odds ratio analyses were conducted to identify key nodes and quantify associations. RESULTS: Sociodemographic variables (e.g., age, sexual orientation) showed more direct connections to mental health outcomes, whereas social determinants (e.g., housing instability, employment) occupied more distal positions. Cannabis use disorder and psychological distress emerged as key bridging nodes linking sociodemographic and structural domains to broader mental health outcomes, including suicidal ideation and alcohol use disorder, suggesting pathways through which contextual risk translates into psychological vulnerability. CONCLUSIONS: Mental health outcomes are shaped by both individual and structural factors. Targeting key bridging nodes (e.g., cannabis use disorder and psychological distress) may improve prevention and intervention, alongside policies addressing adverse social conditions.
